A
It is a remnant or trace of a plant, an animal, or other organisms that may have been replaced by rock material or left imprinted on a sedimentary rock deposited in riverbeds or on the ocean floor.
Fossils
The gradual change and development of a species on a group of organisms that leads it to more advanced form.
Evolution
The building blocks of matter.
Atom
The fundamental unit of life.
Cells
Individuals with traits suited to the environment are more likely to survive than less suited individuals.
True or False?
True
They are scientist who collect, identify, and study pieces of evidence about earlier life-forms and try to determine how these have evolved into the organisms of today.
Paleontologists
It is the branch of biology that studies heredity and variation.
Genetics
Groups of similar cells working together for a specific function.
Tissues
The biochemical composition of organisms is essential in interacting with other organisms and their environment.
True or False?
True
Survival for existence does not depend on the hereditary constitution of survivors, and this is a part of the process of natural selection.
True or Flase?
False
A very small and can be seen only with the aid of a microscope.
Microfossils
The science of grouping organisms according to their presumed natural relationships.
Taxonomy
Group of organisms of the same species living in one area.
Population
Group of tissues and other structures that perform a specific function.
Organ
The second largest group. It divides organisms into major categories like Animals, Plants, Fungi, Protists, etc.
Kingdom
Fossils that are considered the oldest on Earth.
Stromatolites
The Father of Taxonomy
Carolus Linnaeus
It consist of various groups of organisms and the physical components in a particular environment in which particular organisms interact.
Ecosystem
It is made up of organs. It has several organs that function together.
Organ System
Who is the author of the book "On the Origin of Species by Means of Natural Selection", 1859?
Charles Darwin
The biological or genetic information and characteristics of an organisms are contained in its molecular make-up called ____________.
DNA (Dioxyribonucleic Acid)
Groups organisms based on major body plans or structures.
Phylum
The most specific level of classification.
Species
The highest level of hierarchy. It supports all the ecosystems that harbor organisms and the environment where they live.
Biosphere
The highest and broadest level of classification that separates life into three big groups: Bacteria, Archaea, and Eukarya
